Abstract
The present invention relates to one kind carbonating lead plaster smelting process, its processing step is：After lead-acid accumulator to be disassembled to the lead plaster isolated and be carbonated and flux dispensing automatically, it is sent into oxygen-enriched air smelting stove and carries out melting, produce lead bullion, lead skim and low concentration SO2Flue gas；SO2Flue gas desulphurization system desulfurization qualified discharge is sent after waste heat recovery and dust arrester installation are gathered dust；Lead skim is sold to cement plant for the general waste of vitrifying and does raw material；Lead bullion obtains selling outside lead bullion and the earth of positive pole by electrorefining；Realizing the system of the technique includes oxygen-enriched air smelting stove, apparatus for feeding, pulp water quenching equipment, cooling device, dust collection device and desulphurization plant.The present invention is improved by technological design and system, realizes Pb, Ag, Cu, Sb, the clean and effective recovery of Sn elements.
Description
Technical field
The present invention relates to secondary lead smelting technical field, and in particular to a kind of reviver carbonating lead plaster refining is special molten
Agent.
Background technology
At present, domestic reviver factory is about nearly 300, but up to ten thousand tons of scales is few, and small factory's average productive capacity is
1000 tons/year or so.Domestic reviver producer, production scale is small, and technical merit is low, and most producers use small-sized reflection
Stove is smelted, some small enterprises, and self-employed worker is even smelted using original native stove earth kiln.Specifically smelting process is：By lead metal with
Lead skim ash is mixed into kiln smelting, and substantial amounts of low temperature is that fusible lead metal and founding lead skim carry out pyrolytic semlting together,
Using bituminous coal as fuel in smelting process, anthracite and iron filings are added as dispensing, feed intake about 2-4 tons per stove, average coal consumption 560,000
Gram mark coal/ton lead.These small scales, yield poorly, the reviver factory that technique and environmental protection equipment are simple and crude, the rate of recovery of metallic lead only has
80%, comprehensive energy consumption is up to 600kg mark coal/ton lead, produces and more than 8% is up in a large amount of wastes leaded can not obtain recycling
Utilize, the 50% unrecovered utilization of non-ferrous metal such as antimony.The annual lead for having 100,000 tons of meters is lost in or is discharged into environment, seriously unrestrained
Take resource, consume the energy.
Some advanced countries regeneration plumbing has just moved towards production scale, technique cleaning in the eighties in last century in the world
The road of innoxious benign development.The technological process mainly used is：Old and useless battery → cracking and sorting → lead plaster desulfurization → rotary furnace
Smelting → refining → product.
China was extensive in recent years introduces or independent development Mechanical Crushing sorting old and useless battery technique and equipment, but for
The lead plaster of carbonating does not have highly desirable handling process, and flux also uses composition, the costs such as traditional iron foam higher.
The content of the invention
The technical problems to be solved by the invention are to provide the reviver carbon that a kind of using effect is good, and lead skim is easily purified
It is acidified lead plaster refining special melting agent.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of reviver carbonating lead plaster refining special melting agent, is made up of the component of following weight：Rare earth oxide 50g,
Coke 300g, phosphotungstic acid 80g, lime stone 80g, iron ore 200g, sepiolite 70g, carborundum 40g, flyash 60g, containing lead fume
Dirt 60g, potassium feldspar 40g, magnesia 15g；During preparation, combinations thereof is crushed and mixed.Pressed during use with carbonating lead plaster
Mass ratio 0.5-2:5 ratio mixing granulation, is then fed into smelting furnace smelting furnace.
It is a further object to provide a kind of technique smelted using above-mentioned flux to carbonating lead plaster, bag
Include following steps：
(1) it will be pelletized after carbonating lead plaster and special melting agent progress dispensing by disk pelletizing machine, obtain lead plaster grain,
For the humidity of lead plaster grain 7~8%, particle diameter is 30~100mm, is sent into from charge door in oxygen-enriched air smelting stove and carries out melting；
The selection of wherein carbonating lead plaster should be such that the slag type of caused high-temperature fusion lead skim is calculated as in mass ratio：Pb≤
2%, Fe/SiO2=1~1.4%, Ca0/SiO2=0.4~0.8%；
(2) the oxygen rich gas entrance by the oxygen rich gas needed for oxygen-enriched air smelting stove by oxygen-enriched spray gun from oxygen-enriched air smelting stove
Spray into the oxygen-enriched air smelting stove, the reaction zone temperature for controlling oxygen-enriched air smelting stove is 1200 DEG C -1250 DEG C；
(3) the carbonating lead plaster compound produces lead bullion, high-temperature fusion lead skim and contained after oxygen-enriched air smelting stove melting
Low concentration SO2Flue gas；
It is above-mentioned to contain low concentration SO2Flue gas one-level flue dust and one-level flue gas, wherein one-level cigarette are obtained after cooler cools down
Pelletized again in dirt return to step (1) melting；One-level flue gas obtains two level flue dust and secondary smoke after sack cleaner is handled,
Wherein pelletized again in two level flue dust return to step (1) melting, secondary smoke send desulphurization system handle after again purified device it is net
Tail gas after change directly discharges.
Above-mentioned lead bullion releases ingot casting by the lead mouth of putting of the oxygen-enriched air smelting stove, and base-bullion passes through pyro-refining and electrolysis essence
Refining obtains being enriched with copper dross slag, refining lead bullion and the earth of positive pole；
Lead, copper, tin metal are obtained to enrichment copper dross slag processing recovery, ANODE SLIME TREATMENT is reclaimed to obtain lead, antimony, silver gold
Category.
Above-mentioned high-temperature fusion lead skim releases that outer after water quenching to sell cement plant be raw material by the slag tap of oxygen-enriched air smelting stove；
The oxygen-enriched air smelting stove is vertical rectangular configuration, and its top is provided with charge door, and front side bottom is provided with and puts lead mouth；It is described
The sidepiece of oxygen-enriched air smelting stove is provided with oxygen rich gas entrance, and the oxygen-enriched spray gun is arranged on the oxygen rich air of the oxygen-enriched air smelting stove
At body entrance.
Described put is provided with ventilation equipment at lead mouth and slag tap.
Clean room is provided with the purifier, the clean room bottom is provided with air inlet, and top is provided with gas outlet, described
Filtering Nomex is provided with clean room, gas filtration agent is impregnated with the filtering Nomex, to harmful gas in flue gas
